SSL and Let's Encrypt

Is an SSL certificate really required if I’m just using switches for lights etc?
I can understand if I had door controls on there etc…

It’s required if you want remote access - see the checklist.

If you don’t want remote access, then it isn’t required (it may still be advised).

Ah! I just forward the port on my router and access it via a dynamic DNS address - probably not he most secure means, admittedly. Thanks for the info, I’ll review :slight_smile:

Now you’re passing your authentication details unencrypted. If you ever access HA from a network you don’t control, or across the Internet, you have no idea who can intercept that.
